n + 13 = 21. n = 21 - 13
If you mean 11n = 143 then the value of n is 13
n - 8 = 5 n = 13
n - 13 = 7
There are infinitely many polynomials of order 4 that will give these as the first four numbers and any one of these could be "the" rule. The simplest rule, based on a polynomial of order 3 is T(n) = 60*n^3 - 360*n^2 + 673*n - 360 for n = 1, 2, 3, 4. In order to find this polynomial you need to find the regression equation for the data set (1, 13), (2, 26), (3, 39) and (4, 412). There are also non-polynomial solutions.

13-n=9. i think.
that is pi.there isnt really a variable there it just looks like n
The equation can be written as -7x - 4 = 13 - 6x, where "x" represents the unknown number.
Let 'N' be the number. The sum of the number and 13 is (N+13).The square of the sum of the number and 13 is (N+13)2N2 + 26 N + 169.It's probably easier to add 13 to the number and then square that answer ... less arithmetic.
